CHILDS CONVERTIBLE CARRIAGE.

SPECIFICATION forming part of Letters Patent No. 781,495, dated January 31, 1905.

To a whom 'it may concern.-

Be, it known that I, J EssE A. (J ANDALL, a

' citizen of the United States, and aresident of the city ofNew York, borough of Brooklyn, in the county of Kings and State of New .York, have invented a new and Improved Childs Convertible Carriage, of which-thefollowing is a full, clear, and exact description.

My invention relates toa childs carriage; and the particular objects of my invention are to provide'means for converting such carriage at will into a go-cart or a crib and the provision of means for permitting such changes to be made readily and without complicated adjustment of the parts.

the same. Fig. 3 is-a longitudinalsectional view showing in full lines the parts 1n posi tion for use as an ordinary chllds carriage and showing in dotted lines the parts in position for use as a crib, and Fig. 4: 1s a sectional View of a detail.

In the drawings the front uprights are rep- ]resented by 5, the rear uprights by 6, the sides by 7, the front end piece by 8, and the rear end piece by 9. Each side is formed by means of two series of parallel strips pivoted together at several points 10 and forming what is ordinarily known as a lazy-tongs structure. Preferably each strip used in the sides is pivoted to other strips at three points, as shown; but this is not material. Each of the end strips is pivoted to the uprights 5 and 6, re-

spectively, at the points 11, these points being at the lower part of the sides and being fixed with respectto the upright pieces. The strips placed in the other direction at the end of the side pieces are also pivoted to the uprights 5 and 6 by means of pins 12, working in the vertical slots 13, as shown. The object Application filed March 1,1904. $erial No. 196,039.

of this construction is to permit the upper part of the sides to rise and fall when contracted or expanded, the bottom part remaining stationside pieces are provided With bars 14 and 15,

respectively, which pass directly across thev carriage-body, underneath the same, and each of the other strips of one series is provided with a similar cross-bar 16, passing under the bottom of the carriage and adapted to support the'bottom. At the upper end of the strips at the end of each side piece are additional cross-bars 17 18, having holes passing diagonally through'them for the free passage of the rods which constitute the main part of the end, pieces 8 and 9. The cross-bars 17 and 18 are capable of turning on their axes, and the rods forming the end pieces 8 and 9 are capable of sliding through them, so that the operation of contracting and expanding the side pieces, which necessarily raises and lowers the upper ends of the strips constituting the side pieces, 'willnot be impeded.

. The cross-bars 17 and 18 are adapted to be outwardly in order to permit the cross-bar to be placed in or removed from the ends of the side pieces. ner of accomplishing the same purpose in Fig. 1. There a pin 21 is placed in contact with 'the pin 19 and projects through a slot 22 in.

the bar 18, so that the pin 19 may be reciprocated inthecavity 20, and the cross-bar can be fixed to the side pieces without springing the latter. I do not wish .to be limited to either one of these constructions, as any device may be used foraccomplishing the'same purpose.

Upon the front end, piece 8 is pivoted at;

23 a footboard 24. Apair of chains or other holding device 25 is provided for holding the footlooard inthe positions with respect to the I have also shown another manend pieces shown in dotted lines in Fig. 3 and in full lines in Fig. 1. On account of the position of the points at which the chain 25 is secured to the frame this chain constitutes means for holding the footboard perpendicular to the end piece when the latter is swung down to the position shown in Fig. 1 and for holding it at an angle, as shown in Fig. 3. Another pair of chains, 26, is also provided for the purpose of holding this end piece in the position shown in dotted lines in Fig. 3. When the end piece is to hangdown, as shown in Fig. 1, the chains 26 are disengaged from the end piece and hang loosely down from the uprights 5, as shown. Another pair of chains, 27, may be employed for the purpose of holding the rear end piece 9 in the position shown in dotted lines at the left of Fig. 3. The bottom of the body of the carriage is preferably composed of two pieces 28 and 29, one of which is intended to slide over the other when the parts of the carriage are contracted into the position shown in Fig. 1. These two pieces are each secured to one of the rotatable cross-bars 16, as shown in dotted lines in Fig. 3, and they are adapted and intended to rest upon the others of these bars. By having the bottom rest on these bars, which are independent of the pivots, it will not interfere with the operation of the lazy-tongs, will allow folding up into closer quarters than if it rested on the pivots, and will allow tightening of the parts without interfering with the operation.

Upon the outside of the front uprights 5 are placed pins 30, which, with the help of the locking device composed of the two parts 31 and 32,- are used for the purpose of holding the parts in any of the desired positions. The two parts 31 and 32 are pivoted or hinged together at 33, and the part 31 isprovided with two notches 34, the part 32 being provided with a pin 35 for holding the two parts in rectilinear position, as shown in Fig. 3. One of the notches 3A is intended to be used for engagement with the pin 30, as shown in Fig. 1, and the end of the part 32 is provided with a book 36 to engage with the pin 30, as shown in Fig. 3.

37 is a latch used for holding the parts 31 or 32 in locked engagement with the pin 30. (See Fig. 1.)

The bars 31 and 32 are connected to the uprights 5 by swinging them on their pivots and drawing the uprights to the proper point, when the hooks 36 or notches 34 may be slipped over the pins 30.

It will be seen from this description that a vehicle constructed as described will when the parts are placed in the position shown in Fig. 1 constitute a go-cart of convenient and desirable shape, that when placed in the position shown in Fig. 3 in full lines with the rear end piece 9 either in the position shown in full or in dotted lines in said Fig. 3 a crib will be produced, that when placed in the position shown in Fig. 3 in dotted lines a longer crib will result, while the device may also be closed up to a smaller compass than is shown in any of the figures to cause it to take up less room when not in use. In all these positions the parts are firmly secured together, and there is no danger of their disengagement. The changes may be made very easily and without the use of instruments of any kind. The construction of the slots 13 and the passsages through the cross-bars 17 and 18 cause the changes in the vehicle to be very easily made.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A body having longitndinally-extensible sides, a pivoted front piece, a pivoted back piece, and means for securing said front piece and back piece in different positions.

2. A body having a pivoted front piece, a pivoted back piece, a footboard attached to said front piece, and means for securing said front and back pieces in an upright position to close the ends of the body.

3. A body having a pivoted front piece, a pivoted back piece, a footboard pivotally attached to said front piece, means for securing said front and back pieces in different positions, and means for securing said footboard in a plurality of positions.

4. A carriage having an end piece provided with longitudinal rods, and a cross-bar capable of sliding with respect to said rods.

5. A carriage having a pivoted end piece comprising rods and a cross-bar through which said rods loosely pass.

6. A carriage having a pivoted end piece comprising a cross-bar and rods loosely passing through said cross -'bar, and extensible sides connected with said cross-bar.

7. A carriage having a pivoted end piece comprising a cross-bar and rods loosely passing through said cross-bar, extensible sides connected with said cross-bar, and means for disconnecting said sides from said cross-bar.

8. A carriage having a rear end piece, and a front end piece, each comprising a crossbar and longitudinal rods loosely connected thereto.

9. In a carriage, the combination of uprights, extensible sides each made up of two sets of pieces, certain of the' pieces on the ends of said sides being pivoted to said uprights, others of the end pieces having movable connections with said uprights, and an end piece pivoted to said uprights and comprising longitudinal rods and cross-bars.

10. In a carriage, the combination of uprights, extensible sides made up of two sets of parallel pieces, a pivotal connection between said sides and said uprights and an additional movable pivotal connection between said sides and said uprights, an end piece pivoted to said uprights, and means for disconsaid uprights, front and rear end pieces pivr.

oted to said sides, said end pieces comprising a cross bar and longitudinal rods passing loosely through said cross-bar, and means for connecting said cross-bars to said side pieces and for disconnecting them therefrom.

12. The combination of a body comprising extensible -side pieces each made up of two sets of parallel pieces crossing each other at a pluralityof points and pivoted together at the crossing points, cross-bars on said pieces below the pivotal points, and a bottom resting on said cross-bars.

- 13, The combination of a body comprising extensible sides made up of: two sets of parallel crossing pieces extending below the crossing points thereof-, cross-bars on one set of said pieces located below the crossing points of said pieces, and a bottom formed of a plurality of pivoted parts adapted to rest on the cross-bars and to overlap each other.

In testimony whereof I have signed my name to this specification in the presence of two sub- 3 scribing witnesses. v I
